In enzymology, a N-malonylurea hydrolase (EC 3.5.1.95) is an enzyme that catalyzes the chemical reaction

3-oxo-3-ureidopropanoate + H₂O malonate + urea

Thus, the two substrates of this enzyme are 3-oxo-3-ureidopropanoate and H₂O, whereas its two products are malonate and urea.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is 3-oxo-3-ureidopropanoate amidohydrolase (urea- and malonate-forming). This enzyme is also called ureidomalonase.
